Even though this is offtopic I'll answer: Not going to happen.
Nvidia hates OpenCL as it eats their Cuda business and Intel performs market segmentation, therefore their Linux implementation supports only CPU and Xeon Phi and Windows supports the GPU. They don't want server builders to purchase their desktop chips with GPU's. They want them to purchase the massively expensive Xeon Phi and use normal Xeon CPU's.
